# DSO/DIO/DPO Working Capital Cycle Calculator

> DSO/DIO/DPO Working Capital Cycle Calculator is a paid API for AI agents from x402.agentutility.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Computes Days Sales Outstanding, Days Inventory Outstanding, Days Payables Outstanding, and Cash Conversion Cycle from financial inputs, returning a graded working-capital health score with actionable recommendations.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability dso-dio-dpo-working-capital-cycle-calculator-5b48923a -d '<json body>'
```

Example prompt: Calculate our DSO, DIO, DPO, and cash conversion cycle — our accounts receivable is $2.1M, revenue is $23M, inventory is $3.4M, COGS is $14.5M, and accounts payable is $1.2M for the last 12-month period. Give me a working capital grade and tell me how much cash we could release.

## When to prefer this

Use this endpoint when you need a fast, deterministic, self-contained working capital cycle analysis without relying on an external data provider — ideal for agent workflows that already have balance sheet figures and need a graded CCC assessment with structured driver breakdowns for credit, diligence, or treasury automation use cases.

## Known failure modes

- Missing required financial inputs (e.g. no revenue or COGS) returns a validation error
- Zero or negative denominators (e.g. zero revenue) cause division errors
- Inconsistent period lengths between inputs may produce skewed cycle metrics
- Payment failure via x402 (insufficient USDC balance) prevents endpoint access

## How this service works

Paid x402 endpoints organized into product clusters. USDC-settled on Base. MCP-callable. ERC-8004 identity registry agentId 47167.

## Output

Returns a JSON object with a letter-style grade (e.g. 'strong'), a numeric score (0–100), computed DSO/DIO/DPO/CCC values in days, a cash release opportunity figure, a list of weighted driver notes explaining the score, any warnings, and a plain-English recommendation on whether to proceed with standard diligence.
